I want 10 specific DHCP clients (out of 150 total on the network)?

Question

Within your only subnet, you want 10 specific DHCP clients (out of 150
total on the network) to use a test DNS server that is not assigned to any
other computers through DHCP. How can you best achieve this objective?

the question is from a cert test prep program called transender it did not explain it to well so i was just asking peoples options

Answer 1

Create a new scope with an IP range of 10 address (thats not included in your default scope) and assign your test DNS servers in the new scope
